Icons: distinction between on and off (minor issue)
I just now realized, seeing a screenshot on https://gitlab.com/eneiluj/phonetrack-oc/wikis/home that there is obviously a possibility to optically distinguish between activated and deactivated settings when watching sessions: Liek the "show lines" icon. Here are two screenshot of my installation on nextcloud 16, phonetrack 0.5.2:
I can't see any difference in my Firefox 69.0.1. In fact, I never have, because I always click around until all the sessions I want can be seen.
Can anyone confirm that there's no difference?
I can see, that the background-colour is set to some CSS custom property (--color-text-lighter, --color-text-light), but where is it set at all?
